<h1>JMS Failover Without Transactions Example</h1>
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
<p>This example demonstrates two servers coupled as a live-backup pair for high availability (HA), and a client
connection failing over from live to backup when the live server is crashed.</p>
<p>Failover behavior differs whether the JMS session is transacted or not.</p>
<p>When a <em>non-transacted</em> JMS session is used, once and only once delivery is not guaranteed
and it is possible some messages will be lost or delivered twice, depending when the failover to the backup server occurs.</p>
<p>It is up to the client to deal with such cases. To ensure once and only once delivery, the client must
use transacted JMS sessions (as shown in the example for <a href="../transaction-failover/readme.html">failover with transactions</a>).</p>
<p>For more information on ActiveMQ Artemis failover and HA, and clustering in general, please see the clustering
section of the user manual.</p>
